插入铁芯的螺线管自感系数的实验测定及其应用
Measuring self-inductance of solenoid with iron core by experimention and it’s application
【摘要】 通过实验测定,得出了螺线管中插入铁芯后,其自感系数随铁芯插入深度而变化的规律,介绍了利用这一规律制作的电感式位移传感器测量金属杨氏模量的方法.
【Abstract】 The varying rule of self-inductance of solenoid is obtained by experimention measuring when an iron core is inserted in it and a method to measure Young’s modulus of metal by inductive shift sensor made with this rule is introduced.
